Specification of Letters Patent.

Patented Apr. 21, 1914.

Application filed April 15, 1913. Serial No. 761,307.

T 0 all whom it may concern:

Be it known that I, FRANZ TRINKs, manufacturer, a citizen of the Duchyof Brunswick, Empire of Germany, residing at Brunswick, Germany, haveinvented certain new and useful Improvements in Calculat-' ing-Ma-chines, of which the following is a Specification.

My 'invention relates to improvements in calculating machines, and moreparticularly in calculating machines of the type shown and described inmy .prior United .States Patents, Nos.- 928,083, 1,038,464, and1,040,059, ranted, respectively, July 13, 1909, September 10, 1912, andOctober 1, 1912. A shown in these patents, a calculating machine of thistype includes a setting said operations.

With this object in view my invention consists in dividing the settingmechanism into two groups of setting disks and so mounting the saidgroups and their driving mechanisms, that by the rotation of the machinecrank one of the groups of adjustable setting disks can be rotated atwill either in the same direction as the disks of the other group or inthe opposite direction.

For the purpose of explaining the invention an embodiment thereof hasbeen shown in the accompanying drawing, in which the same letters ofreference have been used in all the views to indicate correspondingparts.

In said drawing Figure 1, is a front view of the calculating machinewith the cover of the casing partly removed, Fig. 2, is a verticalcross-section taken on the line 2--2 of Fig. l, andFig. 3 is a verticalcross-section of a detail taken on the line 33 of Fig. 1.

F or the purpose of explaining the invention I have shown a calculatingmachine in which a registering mechanism and a revolutions countingmechanism are mounted in front of, the setting mechanism and on acarriage which is longitudinally shiftable ln-a dlrection parallel tothe axis of the setting mechanism. The general construction of theseparts is known in the art and is shown for example in my aforesaidpatents. Therefore'a brief description will be sulfi- "cie nt for aclear understanding of the invention.

011 a main shaft 4 a setting mechanism is mounted which consists of aplurality of equidistant setting disks 5. The shaft ,4 is adapted toberotated by means of a crank 1 mounted on a shaft 28 through theintermediary of gear wheels 2 and 3. Each of the setting disks 5 isprovided with nine radially shiftable teeth 6 and witha cam disk 7adapted to shift the said teeth inward or outward, the cam disk beingformed with a hand piece 10 projecting through a slit 8 formed in thecover 9 of the casing of the machine. In front of the setting mechanismintermediate gear wheels 11, one for each of the setting disks, areloosely mounted on a shaft 12, and the said intermediate gear wheels areadapted to be rotated by means of the teeth of the setting disks whichhave been shifted outward by their cam disks. The intermediate gearwheels are in mesh with gears 13 connected to numeral wheels 14 whichare loosely mounted on a shaft 15 and .are held at their properdistances apart by spacing sleeves 17. When the intermediate gear wheelsare rotated by the setting disks, the numeral wheels are rotated forwardor backward at angles which correspond to the number set on therespective setting disks 5. .The shafts 12 and 15 are mounted on acarriage 16 which can be shifted in a direction parallel to the shaft 4.The numeral wheels 14 which form the registering mechanism are providedwith carrying devices which have been indicated in the drawing by teeth25 .adapted to be actuated by hammers 19. The carrying mechanism isdescribed more in detail in my aforesaid patents, so that a detaileddescription is not necessary.

At the side of the registering mechanism 14 and (O-RXlElllY therewith amechanism 20 for counting the revolutions of the machine crank 1 isprovided, and the said revolutions counting mechanism is adapted to beturned forward or backward one step for each rotation of the machinecrank by means of a single tooth 21 provided on or rotating with themain shaft 4.

Resetting devices are provided on the registering mechanism andrevolutions counting mechanism, which as shown consist of thumb nuts 22and 23 provided with cam faces 34 and 35 respectively and adapted toshift the shafts 15'and 24 axially at the beginning of their operationand thereby to move radial pins provided on the said shafts in positionfor engagement with noses pro vided on the numeral wheels so as toreturnthe same into their zero positions. Devices of this class are known inthe art, and they have been described in detail in my said patents, sothat a detailed description is not necessary.

Referring now to those parts to which my invention more particularlyrelates, the group of setting disks 5 which are located at the left inFig. 1 are separated from the group of setting disks which are locatedat the right hand part of the machine, so that they can be rotatedindependently of the latter. In the example shown in the drawing thegroup of setting disks which is located at the left of the machine ismounted on a sleeve 26 which is mounted for rotation on the main shaft 4which carries the right hand group of setting disks, and the said shaftand sleeve are adapted to be coupled by means of a clutch member ortooth 27. Apart from this, gear wheels 29, 30, and 31, are providedintermediate the shaft 1 and sleeve 26, which can be thrown into or outof operation and permit the shaft and sleeve to be rotated either inopposite directions or in the same direction.

If it is desired, that the left hand group of setting disks 5 be rotatedin the same direction as the right hand group, a button 30 carrying thecoupling member 27 is shifted in the direction of the arrow shown inFig. 1. Thereby the sleeve 26 is connected with the main shaft 1, andthe aforesaid gearing thrown out of operation, so that upon rotation ofthe machine crank 1 the said sleeve takes part in the rotary movement ofthe right hand group of setting disks mounted on the main shaft. If onthe other hand it is desired that the left hand group of setting disksbe rotated in a direction opposite to that of the right hand group ofsetting disks, the clutch mechanism 27, 36 must be thrown out ofoperation and the gear wheels 29, 30, 31 into operation. By the saidgear wheels the sleeve 26 is connected with the crank shaft 28independently of the clutch 27, 36, and in such a way, that uponrotation of the machine crank 1 the left hand group of setting disks isrotated in a direction opposite to that of the rotation of the righthand group of setting disks, as will clearly be understood from aninspection of the drawing.

As it is necessary to throw the gear wheels 29, 30, 31 out of operationwhen the clutch 27, 36 is thrown into coupling position, or

vice versa, both mechanisms are preferably connected in such a way, thatone of the mechanisms can be thrown into operation only after the otherone is or has been thrown into inoperative position. To indicate whatmay be done for this purpose, the parts 30 and 27 are shown as connectedby a lever 32 having a fulcrum at a point in termediate its ends on arelatively fixed part 38. Therefore, when one of the parts 30 or 27 isthrown into operative position, the other one 27 or 30 is thrown intoinoperative position, or vice versa.
